Other than Besiktas, 5-0 down to Bayern Munich after their first leg, and Sevilla, whose tie against Manchester United is delicately balanced heading into tonight’s second leg and whose odds reflect the impact on the market of all those optimistic United fans, these two clubs are the rank outsiders of the Champions League betting market. Shakhtar are runaway leaders of Ukraine’s Premier League, have won their last six games in all competitions by an aggregate scoreline of 20-1, have one of Europe’s most in-form forwards in Facundo Ferreyra and beat Manchester City in the group stages, but the world is unimpressed. Roma are third in Serie A, and though they trail 2-1 after the first leg the tie seems very nicely balanced. “I think Roma must be both light-hearted and extremely motivated entering this match,” says their coach, Eusebio Di Francesco. “ We must not be cocky but still we must have that strong desire to do damage to our opponents.”
